The variability of Antarctic fast ice extent related to tropical sea surface temperature anomalies

Chen Jiang, Lejiang Yu, Timo Vihma, and Jiechen Zhao

Data sets

Circum-Antarctic landfast sea ice extent, 2000--2018, Ver. 2.2 A. D. Fraser, and R. Massom https://doi.org/10.26179/5d267d1ceb60c

ERA5 monthly averaged data on single levels from 1940 to present H. Hersbach et al. https://doi.org/10.24381/cds.f17050d7

Short summary

This study analyzes the spatial and temporal trends of Antarctic fast ice extent from 2000 to 2018. We also investigate the physical processes through which mid- and low-latitude sea surface temperature anomalies affect fast ice via atmospheric planetary waves, along with seasonal variations in climate forcing mechanisms.
